Benefits of technology

The present invention provides a hot-melt polyester tape with a layers of hot-melt glue, making it stronger and waterproof. The preparation method is efficient and stable, producing high-quality products. The tape can be wound on a multi-head or single-head winder, with small volumes and portability. Additionally, the invention also provides a multi-head winder that can simultaneously wind multiple objects, creating small and portable finished products. The technical effects of the invention are improved efficiency, savings, ease of use, low production cost, and stable quality.

Problems solved by technology

If the partial insulation skin is damaged due to inattention during use, the whole wire may have a problem and even burn out.
This protective film is usually insulating film, this protective film has a large coil diameter when it is finally wound during production, which brings inconvenience to production, and meanwhile there is a need to equip a tape inverter, for handling the protective film coils which may have a bad winding formation or parallel rewinding of the protective film coils into portable forms.

embodiment 1

[0028]As shown in FIGS. 1 and 2, a hot-melt polyester tape comprises a PET film layer 1 which has a thickness of 10 μm, and one side of the PET film layer 1 is coated with a hot-melt glue layer 2 which has a thickness of 2 μm.

[0029]A preparation method of the hot-melt polyester tape comprises the steps:

[0030]1) putting the PET film on a PET film roller 14 of a dry laminating machine 13, drawing the PET film to allow one side of the PET film to pass through a glue bucket 15 containing liquid hot-melt glue layer, and smearing the PET film with the liquid hot-melt glue layer;

[0031]2) drying the PET film smeared with the liquid hot-melt glue layer obtained in the step 1) through a drying tunnel 16 of the dry laminating machine 13 to obtain a semi-finished product, wherein the drying tunnel 16 has 4 heating zones inside, in which the temperature of the first two heating zones is 55° C., and heaters in the latter two heating zones are turned off;

[0032]3) bringing the semi-finished product...

embodiment 2

[0037]As shown in FIGS. 1 and 3, a hot-melt polyester tape comprises a PET film layer 1 which has a thickness of 20 μm, and one side of the PET film layer 1 is coated with a hot-melt glue layer 2 which has a thickness of 5 μm.

[0038]A preparation method of the hot-melt polyester tape comprises the steps:

[0039]1) putting the PET film on a PET film roller 14 of a dry laminating machine 13, drawing the PET film to allow one side of the PET film to pass through a glue bucket 15 containing liquid hot-melt glue layer, and smearing the PET film with the liquid hot-melt glue layer;

[0040]2) drying the PET film smeared with the liquid hot-melt glue layer obtained in the step 1) through a drying tunnel 16 of the dry laminating machine 13 to obtain a semi-finished product, wherein the drying tunnel 16 has 4 heating zones inside, in which the temperature of the first two heating zones is 65° C., and heaters in the latter two heating zones are turned off;

Abstract

A hot-melt polyester tape and a preparation method thereof is provided, the hot-melt polyester tape comprises a PET film layer which has a thickness of 10-20 μm, and one side of the PET film layer is coated with a hot-melt glue layer which has a thickness of 2-5 μm; the preparation method thereof comprises sizing, curing, slitting and winding formation. The hot-melt polyester tape of the invention has the PET film layer and the hot-melt glue layer, and such hot-melt polyester tape is added with a layer of hot-melt glue compared to a conventional PET film, which makes it have higher extension capacity and not easy to break, the extension strength is much higher than the national standard, and the hot-melt polyester tape has the functions of waterproofing and reinforcement.

Description

TECHNICAL FIELD[0001]The following relates to a hot-melt polyester tape and a preparation method thereof.BACKGROUND[0002]Commercially-available thick cables generally contain a plurality of thin wires, which are compactly wrapped up and separated from each other with a thin layer of insulation skin. If the partial insulation skin is damaged due to inattention during use, the whole wire may have a problem and even burn out. In order to avoid above problems, there is a need to wrap these thinner wires with a layer of protective films when fabricating such wires. This protective film is usually insulating film, this protective film has a large coil diameter when it is finally wound during production, which brings inconvenience to production, and meanwhile there is a need to equip a tape inverter, for handling the protective film coils which may have a bad winding formation or parallel rewinding of the protective film coils into portable forms.SUMMARY OF THE INVENTION[0003]In order to s...
